Vertical rendering between activate / deactivate

Question

Hello,

 

I like PlantUML for its commandline rendering.  I use it for Message Sequence Charts.  The graphical style seems to contain a bug, however:

The vertical bars between activate/deactivate start too high and end too high.  The start appears to be aligned with the previous message, so that they stick through ==headers== which is ugly and not necessary.  They also touch a prior arrow, which doesn't improve clarity.  At the bottom, they seem to stop a little above the arrow that ends them, which isn't accurate and also doesn't look as good as it could.

 

Source and rendering demonstrating the problems:

You should try to put the "activate" line after the message, like in:

@startuml
participant User
participant Authn

activate User
User -> Control: Alias Add user+ali@domain
activate Control

Control -> Authn: SecureLayer @domain
activate Authn
Authn -> Control: RemoteID user@domain
deactivate Authn
@enduml

Does it work better for you this way ?

Much better, thank you!

Sorry if I missed that in the manual.
